Operating temperature range:
Nominal temperature range:
Storage temperature range:
The chart of four temperature ranges for the instrument exist to sat-
isfy European Standards requirements; the instrument can be used
over the full Working temperature range by using the temperature co-
efficient to calculate accuracy at the ambient temperature of use.
Temperature coefficient:
Operating errors:
The maximum percentage operating error within the measurement range does
not exceed ± 30 % with the measured value as fiducial value, as determined in
accordance with TABLE 1.
The operating error applies under the rated operating conditions given in
IEC1557-1 and the following:
injection of series interference voltages with system frequencies of
400 Hz, 60 Hz, 50 Hz, 16
across the terminals E (ES) and S. The r.m.s. value of the series inter-
ference voltage shall be 3 V;
resistance of the auxiliary earth electrode and of the probes: 0 to 100 x
R but 50 k ;
A
system voltages between 85 % and 110 % of the nominal voltage and
between 99 % and 101 % of the nominal system frequency for meas-
uring equipment with a mains supply and/or measuring equipment de-
riving its output voltage directly from the distribution system.
